One of the best memoirs of 2006, Alexander Masters’s Stuart: A Life Backwards (Delta, $12), has arrived in paperback, not long after becoming a finalist for a National Book Critics Circle Award. If you don’t think anybody could tell a charming story of the life an “ex-homeless, ex-junkie psychopath,” this book could change your mind. This link will take you to a review that has a reading group guide posted just below it: www.oneminutebookreviews.wordpress.com/2007/03/22/. The readers’ guide is also saved with the March posts and in the “Totally Unauthorized Reading Group Guides” category.
